Got a call from this number at 735 this evening. No one seemed to be on the other end. I am in the 512 area code also. I called the number back and after the 5th try it rang and picked up but no one answered. I kept the line busy a while (15 min) before hanging up.
Barf. Woo hoo! I won a 4 day cruise to Cozumel, only because the jeep cherokee they were giving away was, well, given away so they had this left over - some pleasant lady left a voice mail. Again, barf.
Both my cells have had the same call. It rings, no one answers, leaves no message, registers as a received call, and then continues to be busy if you attempt to recall. Call lasted 14 secs. No name.
